Large and small hierarchies from finite modular symmetries
Tetsutaro Higaki, Junichiro Kawamura, Tatsuo Kobayashi +2
We study the moduli stabilization by the radiative corrections due to the moduli dependent vector-like masses invariant under the finite modular symmetry. The radiative stabilizati…
Spontaneous CP violation and partially broken modular flavor symmetries
Tetsutaro Higaki, Tatsuo Kobayashi, Kaito Nasu +1
We study the realization of spontaneous CP violation through moduli stabilization. In modular flavor models, the source of CP violation is the vacuum expectation values of the comp…
Moduli stabilization in finite modular symmetric models
Yoshihiko Abe, Komei Goto, Testutaro Higaki +2
We study vacua of moduli potential consisting of multiple contribution of modular forms in a finite modular symmetry. If the potential is given by a single modular form, the Minkow…
CP phase in modular flavor models and discrete Froggatt-Nielsen models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu
We study the large mass hierarchy and CP violation in the modular symmetric quark flavor models without fine-tuning. Mass matrices are written in terms of modular forms. Modular fo…

Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study an approach to construct Siegel modular forms from . Zero-mode wave functions on with magnetic flux background behave Siegel modular forms at the origin. Th…
Radiative correction on moduli stabilization in modular flavor symmetric models
Tatsuo Kobayashi, Kaito Nasu, Riku Sakuma +1
We study the radiative corrections to the stabilization of the complex structure modulus in modular flavor symmetric models. We discuss the possibility of obtaining the vacuum…
Moduli trapping mechanism in modular flavor symmetric models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +1
We discuss how the moduli in modular flavor symmetric models dynamically select enhanced symmetry points at which the residual modular symmetry renders extra matter fields massless…
Quark mass hierarchies and CP violation in modular symmetric flavor models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study modular symmetric flavor models to realize quark mass hierarchies and mixing angles without fine-tuning. Mass matrices are written in terms of…
Quark hierarchical structures in modular symmetric flavor models at level 6
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study modular symmetric quark flavor models without fine-tuning. Mass matrices are written in terms of modular forms, and modular forms in the vicinity of the modular fixed poin…
Modular symmetry of soft supersymmetry breaking terms
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +3
We study the modular symmetry of soft supersymmetry breaking terms. Soft scalar masses and -term coefficients are invariant under the modular symmetry when we regard -term as…
